This invention relates to storm windows, and has for its object to provide a simple and eiiicient Window oi this class that is capable of being easily, quickly and economically installed in a window casing. The novel features reside primarily in the manner ci mounting the window members in the casing.

The invention is fully described in the following specification, and a preferred form thereof is shown in the accompanying drawings, in which- Fig. l is a iront elevation of a window casing with a storm window embodying the invention installed therein and in closed position, with a part of one of the window members broken away; Fig, 2 is a similar view fragmentarily shown with the vlower window member partly raised; Fig. 3 is an enlarged cross-section on the line t3 in Fig. l, with parts broken away; Fig. 4 is enlarged section on the line --li in Fig. 2; Fig. 5 is an enlarged vertical section on the line 5-5 in Fig. l, with parts broken away; Fig. 6 is an enlarged fragmentary section on the line 5li in Fig. l; Fig. 7 is an enlarged fragmentary perspective view of a side edge portion of the casing illustrating the manner oi mounting the storm window members therein; Fig. 8 is a fragmentary section on the line 8 3 in Fig. "l, and Fig. 9 is a view similar to Fig. 8 in exploded form.

Referring to the drawings, i designates a customary window casing in which .the usual up er and lower window sash lare mounted, a lower sash being shown at i2 (Fig. 3). The two sash operate, in the present instance, in respective side grooves 3 and il, the outer or weather side of the former being formed by the guide strip Ei at the outer side of which is the usual facing strip 5 of the casing. This strip li and the guide strip 5 cooperate at the sides and also across the top oi the casing opening to form an angled recess l'.

The storl window of the present invention includes upper and lower plate members lll and l I preferably but not necessarily of transparent glass of heavy plate form, with their adjacent horizontal edges lapping so that the lower member, if desired, may be raised relative to the other.

The mounting means for the plate members i@ and H includes a right angled strip I2 tted into the recess I at each side of the casing opening. A similar top strip I2@ is, provided across the top of the casing opening, but this strip; is spaced from the vertical face of the recess wall substantially the thickness of the lower plate member il by a shallow spacing strip I3 (Fig. 5), which strip is substantially the thickness r0f the member II.

Each strip I2 has its outwardly projecting ange l2b of greater width, or extent of outward projection, than the combined thickness of the two plate members Il! and il from its lower end to substantially a level with the lower edge of the upper member It, and is then reduced in depth for the remainder of its length to substantially the thickness of the member ll, as shown at ic (Fig. 6). The top shoulder end of the iiange 52h, at the point where it is narrowed in width, is shown at I2d in Figs. 'l and 8.

A second right angled strip ifi is set into the cutaway portion of the flange I 2b ci each side strip i2 .upwardly from the shoulder i211, the outwardly projecting depth iiange Ma thereof being flush at its outer edge with the outer edge of the ria-nge lib of the strip i2, as best shown in '.l. The width flange iib of the strip lll is the same in width as the corresponding nange IZB of the strip I2 which it parallels. The flanges I2@ and Elib thus form a top runway portion I5 ior the plate member I I when raised.

The top angle strip I2a is similar to the lower portion of the side strips IZ except that its outwardly projecting Vdepth ilange is reduced in depth an extent corresponding to the thickness of the spacing strip I3 (Fig. 5). The width flange of the strip I2a is the same as the flange lib oi the angle strip Iii and vertically aligns therewith.

In the angle of each side strip I2 is mounted an edge spacing piece lli for the respective edge of the plate member II, and it also serves as a means for spacing the inner edge portions of the two cooperating strip iianges I2e and Ib (Figs. 3, 6, 'land 8). These strips i6 align with the top spacing strips I3. A spacing strip l5 (Fig. 6), similar to the spacing strips It, is mounted inthe angle of each'angle strip li in engagement with the respective edge of .the plate iii. The angle strips I2, 52e and lll, and the spacing strips I3, I5 and Ita are secured to the casing by 4hrads il, or in any other suitable manner.

The upper plate member lll is held in position against the width or inwardly projecting iiange of the top angle strip I2a and against the corresponding lnanges Itb oi the side angle strips i4 by respective outer clamping strips 2li that seat at their outer edges relative to the casing opening on the outer free edges of the depth iianges of the respective angle strips i2@ and Ill. These clamping strips, starting a short distance inward 'from their outer edges, extend inwardly on an incline. toward, and bear at their free inner edge portions against, the outer face of the upper plate member I@ in opposition to the width flanges Ida of the side angle strips III and the corresponding ange of the top strip |25. The clamping strips 20 are drawn into clamping engagement with the plate member by screws 2i that are inserted through suitable openings in the strips 2l) and the respective angle strips Iliand screw into the casing, as shown in Figs. 5 and 6. The screws extend through the strips l2a and I4 at approximately the angles thereof and are inclined to the plane of the plate member IIJ, as shown. The top and side strips have mitered engagement at their meeting ends.

The lower plate member II is held in position in its runway l5 by side clamping strips 22 which are similar to and preferably made separate from i the strips 2Q for convenience of assembly. The strips 22 are the same as the strips 20, aligning vertically therewith, and in addition are provided at their inner edges with lips 23 (Figs. 3 and 7), which have edge engagement with the plate I I and compensate for the combined thickness of the top plate It and the angle strip flanges Mb. The strips 22 are drawn into clamping engagement with the plate member I l by screws 24 in a manner similar to the action of the screws 2l. The clamping of the plate member l l is not so iirm but what it can be raised and lowered in the runway I5 if desired.

The lower end of the plate member I I ts into and is firmly clamped by a U-shaped edge strip 24 the outer upper edge of which is doubled back to form a downwardly opening recess 25 for reoeiving an upstanding mating ange 25 cn the casingsill S, thus foming a weather-tight joint therebetween when the plate member is lowered.

The flange 2G has a base flange 21 for seating on the casing sill and is secured thereto by screws 28. The various strips forming the mounting, guiding and clamping means for the plate members i8 and Ii are preferably bit not necessarily of metal, and the spacingstrips I3, I6 and IE5a are preferably of wood.' These strips may be quickly assembled in a window casing by rst mounting the side angle strips I2, top spacing strips I3 and top angle strips I?a therein, the parts being secured in position by the use of brads, or in any other suitable manner. The side angle strips ill are then secured to the spacing sides at the upper end portions of the side angle strips I2 in the upper recessed or cutaway anged portions thereof with the width flanges I 4b of the strips I4 bearing inwardly against the spacing strips IE. The plate member II may now be mounted for sliding movements in the guide spaces I5 which are formed between the width f' anges I2e and Mb of the angle strips I2 and I4. The upper plate member IU may also be placed inwardly against the width anges Mb of the angle strips i4 after rst positioning the spacing strips i611 in the angles of the strip I4. rThe securing of the plate members I0 and II in the casing may now be completed by simply positioning he clamping strips 29 across the top of the casing opening and along the sides thereof in clamping engagement with the member I0 at their inner edges and with the outer edges of the depth flanges Ha of the strips I4 at their outer edges, these clamping strips being secured in position by insertion of the screws 2I. 'Ihe lower member is also clamped in its runway by attaching the lower clamping strip members 22 in position by use of the screws 28 with the inner lip edges 23 thereof bearing against the member II and their outer edges bearing inward against the outer edges of the respective anges I2".

It is apparent that the mounting and holding means for the plate members may be easily and quickly attached to a casing member in plateholding relation, and that the whole constitutes an exceedingly simple and economical mounting for storm window members.

I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of numerous modifications and changes without departing from the spirit of the claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent, is:

1. The combination with a window frame or casing having a marginal recess at the sides and top of its window receiving opening, a mounting for a storm window comprising upper xed and lower movable plate members in said opening, a rst angle strip secured in the sides of said marginal recess, said angle strip having a reduced edge above the top of the lower plate, a second angle strip having a length equal to the height of the upper plate secured in the marginal recess over the upper portion of the first mentioned angle strip, spacing strips in the inner corners of each of said angle strips, a spacing strip along the top of the window recess and an upper angle strip mounted in said recess over said spacing strip, clamping strips secured in said marginal recess for retaininqt the upper and lower plates in the channels formed by the two side angle strips and said top angle strip.
